Dog owners are being urged to stay vigilant amid reports from residents that gangs of thieves are operating in Cambridgeshire.

Earlier this month, a dog was stolen from a house in Eastfields, Littleport, and residents in Stretham and Little Thetford have reported suspicious vehicles loitering in cul-de-sacs in the past week.

Police were also made aware of suspicious activity in Needingworth and St Ives on Monday, with allegations that groups of men were knocking on doors posing as builders in order to scout for dogs.

A dog owner living in Ely Road, Stretham, said: “I came home from work one evening and there was a group of people sitting in a car right outside our gate, which had been left open, which is very, very unusual.

“Where we live, it is a dead end road so there is no need to go there unless you live there. The car was a dark coloured BMW and it was there at about 8pm, we reported it to police. We were told by friends that a similar car was spotted in Little Thetford.”

The homeowner added that, on the same evening the car was spotted outside his house, chalk markings appeared on his fence, prompting fears that his house, and his dog, had been marked out by potential thieves.

He added: “I think it is important to get the word out there so that people are aware.”
